Police have been urged to start a murder inquiry into Dr David Kelly’s death following further allegations that he did not commit suicide.

Officers have been told the government scientist could not have taken an overdose of painkillers.

This overdose was found by the original pathologist to be one of the causes of his death.

Dr Andrew Watt, an experienced clinical pharmacologist, says he has told Thames Valley Police it is not possible Dr Kelly could have swallowed more than a ‘safe’ dose of two coproxamol tablets because there was so little in his system after death.

He said: ‘I reported to the Thames force that I believe that the death of Dr Kelly may have been murder. I have received an acknowledgement and they have given me an incident number.

‘I have been told that the inquiry is being conducted by a very senior officer.’
A second development also casts doubt on the suicide verdict of the Hutton inquiry – which took the place of a formal inquest.
